AUTOMATIC TIME-CONTROLLED REGULATOR FOB GAS-ENGINES.

Specification of Letters Patent.

Patented Mar. 19, 1912.

Application filed July 27, 1911. Serial No. 640,819.

To all whom it may concern Be it known that I, WALTER CALVIN GAM- BnnL,a citizen of the United States, residing at Tabor, in the county oiDewitt and State of Illinois, have invented new and useful Improvementsin Automatic Time Controlled Regulators for Gas Engines, of which thefollowing is a specification.

This invention relates to an automatic time-controlled regulator for gasengines or the like, and its objects are to provide a device of thischaracter which is adapted for use particularly upon engines or likemotors which are used for driving mill engines or the like, and meanswhereby the throttle of the engine and the electric sparking device canbe connected with the device to be operated thereby at a predeterminedtime, entirely cutting oil the engine without requiring the services ofan attendant.

In the drawing, forming a portion of this specification and in whichlike numerals of reference indicate similar parts in the several views:Figure 1 is a perspective view of the device applied to a gas engine andto the sparking mechanism therefor, a conventional form of engine beingshown simply for the sake oi illustration. Fig. 2 is a perspective viewof the latch mechanism.

The engine A shown herein is of the gasolene-controlled type, beingprovided with a throttle lever B and an electric sparking device C. Thesparking device may be a suit-- able storage battery, a magneto or thelike and is operatively electrically connected with the spark plug ofthe engine, the said sparking device being provided with a controllingswitch D, as shown.

The automatic controlling device comprises av clock 1 or any othersimilar well known construction which will include a movable partto beactuated at a predetermined time, the alarm mechanism of the clock shownherein being the part of the mechanism relied upon in the presentinstance for actuating the movable element of the latch. The latchcomprises a fixed member 2 and a movable member 3, both of which beingprovided with interfitting notched portions 4:. The element 3 of thelatch when operatively connected with the fixed element 2 has its curvedactuating surface 5 disposed in juxtaposition with the tapper 6 of thealarm mechanism shown, so as to be engaged by the tapper when the latteris engaged on the sounding of the alarm.

A guide member 7 is fixedly supported to a wall or other suitablesupport, being disposed below the timing mechanism 1, and asillustrated, said guide member has slidably mounted therein a flexiblecontrolling element 8 such as a cable. The upper end of the cable isconnected, at 9, to the movable element 3 of the latch. The opposite endof the cable has connected therewith a weight 10. The controlling cableis connected with supplemental controlling cables or similar suitableflexible connections 11 and 12, the latter being slidable in the guide13 and provided with a looped terminal 14 which is adapted to beextended over the throttle lever B of the engine. The cable 11 isprovided with a looped terminal 15 which is adapted to be extended overthe switch D of the spar-king mechanism hereinbefore described. Thecable 11 is provided at the point above the guide 16 with a stop 17which is designed to engage the guide so as to limit the slidingmovement of the cable under the tension of the weight 10. The cable 12is provided with a similar stop 18 which is designed to engage the guide13, as shown.

In operation of my improved time-controlled mechanism, the loopedterminals 14: and 15 are placed over the switch 1) and throttle lever Bof the engine. Theelement 3 of the latch is engaged with its co6peratingelement 2 and disposed in the path of the t apper so that on movement ofthe latter it will actuate the element 3 of the latter, disengaging thesame from the stationary element 2. This permits the weight 10 to drawdownwardly on the cable 8 and to correspondingly act or draw upon thecables 11 so as to simultaneously control the throttle lever and theswitch piece D. The stops 17 and 18 respectively, while being adaptedfor cooperation with the guides 13 and 16 will be engaged thereby so asto limit the movement of the cables 11 and 12 when drawn upon throughthe tension of the weight 10 and thereby hold the loop portions 14 and17 in relative close proximity with their engaging levers so as topermit of their being conveniently and quickly engaged therewith afteroperation of the device.

I claim:

An engine stopper comprising flexible connections having looped endsadapted to be extended over the throttle lever and the movable switchpiece of the sparking device respectively of the engine, means forguiding the connections in their sliding movements and for limiting thesliding movements of said connections, a gravitating member for movingthe first connections to operative posit-ions, a flexible connectionconnected With the said gravitating member, a fixed member disposedabove the gravitating member, and time-controlled means on the flexibleconnection of the gravitating member and adapted for removable engagement With the said fixed member whereby the said gravitating member isheld against movement in one direction.

I11 testimony whereof I aflix my signature in presence of two Witnesses.
